Is well known that above all DMOZ directory is the best online directory. DMOZ, also known as The Open Directory Project (ODP), is a large, categorized directory of websites and pages, which is staffed by volunteers. Every website and page that is added to the directory has to be manually reviewed before it is included. Being listed in the directory is free.
But when you try to list your site in DMOZ you are in trouble. After you add your site an editor will approved it ... or not. And this can take months, even years.
So what is the solution ?
A good alternative until your site is listed to DMOZ is to submit your site to online free web directories. Submitting site to online free web directories will fast increase your PageRank. PageRank is an integral part of Google's ranking algorithm, and higher PageRank helps towards higher rankings. The PageRank within a website is increased by pages from other sites linking to it, and the higher the PageRank of the pages that link to it, the better it is for the receiving site.
When submitting a site to online free web directories, always take time to find the right category for it. Don't be tempted to submit it to a category that is higher up the tree than it belongs, because it won't be accepted there and, doing so, could cause unnecessary, self-induced delays.
